Description
Technical Field

Background
The lighting device sold in the current market has single function and low intelligent degree, and cannot meet the increasing complex lighting demands of people.

The automatic induction lighting method of the invention can be divided into three working modes, namely: intelligent control mode, special control mode, and sleep control mode. The control circuit controls the lighting circuit to be turned on/off according to the intelligent control mode, the special control mode or the sleep control mode.
The working process of the intelligent control mode is as follows: when the photosensitive sensor detects that the ambient light intensity is insufficient and the pyroelectric infrared sensor detects that a person exists, the lighting device is started, and the timer starts to count. During the period, if the pyroelectric infrared sensor detects that a person exists, the timer counts to zero, otherwise, the lighting device is turned off when the timer counts to a set value; if the pyroelectric infrared sensor does not detect a person, after the timer reaches a set value, an active detection function (an active detection function, namely, an MCU controls a stepping motor to rotate so as to drive the pyroelectric infrared sensor to rotate and generate relative displacement with a human body) is started. If the person is actively detected, the timer counts to zero and stops active detection, and the pyroelectric infrared sensor is started for detection, so that the cycle is performed; if the active detection does not detect the existence of a person, the lighting device is turned off, the pyroelectric infrared sensor is started to detect, and the next trigger is waited.
The working process of the special control mode is as follows: in this mode, the user can turn on/off the lighting device by voice message such as turning on or off the light through voice input without obtaining the ambient light intensity. In this mode, if the pyroelectric infrared sensor detects a person, the lighting device maintains the lighting state input by the user, and the timer starts to count. During the period, if the pyroelectric infrared sensor detects that a person exists, the timer count returns to zero; if the pyroelectric infrared sensor does not detect someone, the active detection function is started after the timer reaches a set value. If the person is actively detected, the timer counts to zero and stops active detection, and the pyroelectric infrared sensor is started for detection, so that the cycle is performed; if the active detection does not detect the existence of a person, the lighting device is turned off, and the intelligent mode is switched to, so that the lighting device is conveniently turned on automatically when entering a room next time. The mode is suitable for people with special requirements, such as when the lights are turned on in daytime, when the curtains are turned off in daytime, when the lights are turned off to watch television, a movie or when the lights are forgotten to be turned off, the full-automatic requirements can be met.
The working process of the sleep control mode is as follows: the lighting device can be used as a small night lamp (only part of the lamp beads are on) and can adjust the color temperature and the brightness through voice control so as to meet the preference of different users, and the lighting device can be switched to a special mode to turn off the lamp for sleeping when the lighting is not needed. In this mode, if the pyroelectric infrared sensor detects a person, the lighting device is kept in a small night lamp state, and the timer starts to count. During the period, if the pyroelectric infrared sensor detects that a person exists, the timer count returns to zero; if the pyroelectric infrared sensor does not detect someone, the active detection function is started after the timer reaches a set value. If the person is actively detected, the timer counts to zero and stops active detection, and the pyroelectric infrared sensor is started for detection, so that the cycle is performed; if the active detection does not detect the existence of a person, the lighting device is turned off, and the intelligent mode is switched to, so that the lighting device is conveniently turned on automatically when entering a room next time. When the lighting device is installed in a bedroom, the intelligent mode can not be turned off when a user needs to sleep at night, the user can switch to the sleep mode through voice, the lighting device can serve as a small night lamp, and the color temperature and the brightness can be adjusted.
